TCP/IP and missing SYS$REM logicals?

I'm using OpenVMS version 7.2-1 with TCP/IP version 5.0A.
I have programs that log into the machine and redisplay the output at the
requesting computer (Vax,Alpha,UNIX). One particular Alpha returns a NULL for
the strings: F$TRNLNM ("SYS$REM_ID") and ("SYS$REM_ID") during a Telnet
session. This is the newest
of my Alphas with the most recent software. All the others return values as
documented.
Was there a change that got rid of these strings?

The Answer is :

This appears related to a known problem in TCP/IP Services V5.0A process
creation, and that problem has been addressed in the V5.1 release.
